Besides being pretty lethal................the bottle rocket robot would be a big job to construct, aim etc. You would need a lot of different systems to interact, and the forces involved are hard to predict/use.

Plus, if i'm thinking of the same rockets as you, water is a good idea to propel the rocket? Robots + water doesn't sound too great.

I'd say go for multiple projectiles like tennis balls, potatoes or very very small mushrooms.

My first thought when seeing your post was a parade-bot that participates in a Fourth of July parade. No ethical issues there, unless you consider the particulate matter and greenhouse gases that are emitted in the process. Also, a large enough quantity of bottle rockets might launch your UAV into low-earth orbit, though perhaps there are more efficient (and cleaner) means.

lol, the worst firework accidnt i've ever had was: getting shot in the leg with what i thought was a dud, puttin aeiral shells in backwards.....Twice, or having a firecracker explode about a half inch from my hand(boy i hate those black cats)

it actually kind of funny because each year its on the news about fireworks being illegal, and the only restriction i get is my mom not letting us get bottle rockets.

Now what would happen if we equipped a robot with a high resolution camera and plenty of bottle rockets with a garunteed ignition source, and had it programmed to shoot at moving things..... would that be ethical

gamefreak, if your mom won't let you buy bottle rockets because she thinks they are dangerous, then you could build a robot that lights them and shoots them off and she might let you get them, and then when she isn't around you can have some real fun with them

IMPORTANT: Amin please do not Ban me for this post I'm just exercising my mind.

I think at this point we have blown our noses with ethics and tossed out the window so now I feel it is a good time for my two cents . The concept you want to examine for the guidance system would be Proportional Integral Control see: http://en.wikipedia.org/wiki/Proportional-Integral-Derivative_controller . This would give you the varying position of the moving object and one could derive a lead time for the shot. a high res camera wouldn't be needed just tie in some radio-frequency proximity detectors into a network of LM380 Op-Amps to decide which direction the robot should aim. If(mov_obj = FrontSensor) { Fire(1); Return 0;} . I look forward to reading of your arrest on the news .

lol, fun fun fun, Also my mom wont let us get bottle rockets(except the bigs one that fly way up there and have the big effects) because she thinks i'll start a fire.

Doesn't the army have radio controlled robots incorporated with some things? and arent robots slowly making there way into every part of our lives? wait.... OH NO..... ROBOTS ARE TAKING OVER, QUICK EVERYONE GET AN EMP GUN
